问题 In the following text, some sentences have been removed. For Questions 41-45, choose the most suitable one from the list (A、B、C、D、E、F、G……) to fit into each of the numbered blank. There are several extra choices, which do not fit in any of the gaps. (10 points)

    (41)______. But traffic experts say building more roads is a quick-fix solution that will not alleviate the traffic problem in the long run. Soaring land costs, increasing concern over social and environmental disruptions caused by road building, and the likelihood that more roads can only lead to more cars and traffic are powerful factors bearing down on a 1950s-style construction program.
    (42)______. Proponents of this advanced technology say electronic detection systems, closed-circuit television, radio communication, ramp metering, variable message singing, and other smart-highway technology can now be used at a reasonable cost to improve communication between drivers and the people who monitor traffic.
    Pathfinder, a Santa Monica, California-based smart-highway project in which a 14-mile stretch of the Santa Monica Freeway, making up what is called a "smart corridor", is being instrumented with buried loops in the pavement. Closed circuit television cameras survey the flow of traffic, while communications linked to properly equipped automobiles advise motorists of the least congested routes or detours.
    (43)______.
    "Electronics on the highway addresses just one aspect of the Problem: how to regulate traffic more efficiently", explains Michael Rennet, senior researcher at the World watch Institute. "It doesn’t deal with the central problem of too many cars for roads that can’t be built fast enough. It sends people the wrong message: They start thinking ’Yes, there used to be a traffic congestion problem, but that’s been solved now because we have an advanced high-tech system in place. ’" Larson agrees and adds, (44)"______".
    Other traffic problem-solving options being studied and experimented with include car pooling, rapid mass-transit systems, staggered or flexible work hours, and road pricing, a system whereby motorists pay a certain amount for the time they use a highway.
    (45)______.

A. Smart highways are just one of the tools that we will use to deal with our traffic problems. It’s not the solution itself, just part of the package. There are different strategies.
B. It seems that we need a new, major thrust to deal with the traffic problems of the next 20 years. There has to be a big change.
C. It’s taking advantage of the technology you use in your everyday lives and putting it to work on highways.
D. Traffic statistics paint a gloomy picture. To help solve their traffic woes, some rapidly growing U.S. cities have simply built more roads.
E. The goal of smart-highway technology is to make traffic systems work at optimum efficiency by treating the road and the vehicles traveling on them as an integral transportation system.
F. Smart highways that will allow a driver to program a destination on a dashboard computer, then sit back and enjoy the ride.
G. Not all traffic experts, however, look to smart-highway technology as the ultimate solution to traffic gridlock. Some say the high-tech approach is limited and can only offer temporary solutions to a serious problem.
